delete sync.ffs_lock immediately after Sync

[mooseifert]

Is there any way, you could set up the program to delete the lock files right
after the sync procress is finished? I spent 1/2 my backup time deleting 1000s
of lock files from folders because i forget to close ffs before unplugging
computers or drives. Alternatively, could you implement an option of disabling
lock files alltogether because they are driving me up the wall, frankly.

There is a similar issue reported here [404, Invalid URL: https://sourceforge.net/tracker/?func=detail&aid=3166021&group_id=234430&atid=1093083]
I acknowledge this issue and will try to find a decent solution.
